"This is the first step. This is not the end, this is the beginning," Garner's mother, Gwen Carr, told a crowd Saturday at a rally in Washington, D.C.

A day earlier, it was reported that Lynch will not complete the Justice Department's investigation into Garner's chokehold death in 2014. The DOJ will neither charge nor clear the NYPD officers involved within the next week, people familiar with the matter told The Washington Post.

Carr was joined by the mothers of Trayvon Martin and Walter Scott at the rally organized by the Rev. Al Sharpton.
